The OKITYPER-2000 was developed in 1960 in response to the need for a typewriter that was smaller and more feature-rich than conventional perforation typewriters. The desktop multifunction electric typewriter had additional paper tape reading and punching functions, but its primary application was as an I/O device for computers. It was a best-seller in its time, with about 20,000 units manufactured between 1961 and 1980.
The OKITYPER-2000 had around 2,000 parts and its typebar printing method had sufficient impact force to create 10 duplicate sheets at a time. It could print 500 letters, numbers, or kana characters per minute. Oki Electric used an array of small relays for many functions that had previously been done mechanically in order to reduce the size of the OKITYPER-2000.
